MACUSER UPGRADE AN OLDER IMAC’S PCIE SSD

latches. You must
press these to
enable removal
and the large
cable requires a
fair amount of
force. Don’t just
yank.

5. There are
   upward-facing
   screws behind the
   fan that are easy
   to forget. These
   are also slightly
   different from the
   others with a
   raised secondary
   flange beneath the
   actual screw head.
   Remember
   how I brought up the fit issue with the
   Sinetech adapter? I was able to screw the
   assembly in place by tilting the screw with its
   tip just in the hole, then pressing it towards
   the assembly. This did unfortunately induce
   a bit of a bow in the SSD, but shouldn’t be a
   problem. If you’re brave, you can deepen
   the adapter’s and SSD’s indentations a bit
   with a round file and much care.
   Once you have the drive installed and
   are ready to test it, I recommend that you
   only do the bare minimum of reassembly
   (minimal screws, leave the display
   untaped, no speakers, etc.) so that you

don’t have to repeat the entire

disassembly again should something be

amiss with the drive or the procedure

otherwise doesn’t work.

When the computer is operational

again, boot with the USB disk you created,

run the High Sierra Disk Utility to partition

the drive and you should be on your way.

Then complete the reassembly process.

WHICH COMPUTERS,

WHICH DRIVES

There is no PCIe SSD slot in 21.5-inch

iMacs that didn’t ship with Fusion Drives or

A completely useless picture of what a late 2015 27-inch iMac looks like

with the components removed. Just to prove I actually disassembled it,

as well as ignored my own advice about a large workspace. And darn if

Apple’s AIO’s don’t look better empty than others do assembled.
